[Rsiena-help] Error in initializeFRAN

[Tom Snijders]

Dear Eli,

This kind of question should rather be addressed at the Yahoo Siena/Stocnet list,
http://groups.yahoo.com/groups/stocnet/

I do not know what is happening here. My first guess is that some of the team data sets is incorrect. Try to figure out more precisely when the error occurs: start with two groups with identical wave count, then add more groups, etc.

Best wishes,
Tom

Subject: [Rsiena-help] Error in initializeFRAN

Hello...I’m having a problem running a model with a sienaGroup object (~30 subnetworks, 4-5 nodes in each).  Each team has the same data arrangement (one dependent, 9 coCovar and 2 coDyadCovar), but differ somewhat in terms of waves and node count.

I can process models for each of these teams individually, but trying to run siena07 with the group object, it returns:

Error in initializeFRAN(z, x, initC = FALSE, ...) :
  INTEGER() can only be applied to a 'integer', not a 'list'

My relevant code is pretty basic at this point:
######################
#previously created siena objects for each team, run fine individually
usableGroups <- list(team107,team108,team110,team111,team112,team113,team114,team115,team116,team118,team119,
                                          team122,team123,team127,team129,team130,team131,team132,team134,team136,team138,team139,
                                          team140,team142,team143)

minuteFirstGroup <- sienaGroupCreate(usableGroups)
minuteFirst.effects <- getEffects(minuteFirstGroup)
minuteFirst.algorithm <- sienaAlgorithmCreate()

test <- siena07(minuteFirst.algorithm, data = minuteFirstGroup, effects = minuteFirst.effects, verbose = TRUE)
##########################

I’m using version 1.1-294 of RSiena(), which I downloaded from R-Forge, and I had the same issue with the CRAN version.  I looked through the code for robmon() and initializeFRAN() on GitHub, but I can’t quite figure out where the glitch is.  Any thoughts or pointers?

Thanks in advance!
